Gaming laptops tend to have replaceable RAM and SSD so the advantage of Framework 16 is much less.
The current benefit for a Framework is that you can swap out the entire inner/guts without being an expert and everything still works together. Most of the laptops I have provide 2 SO-DIMM slots and a slot for either NVME or SATA for storage.
So for me, there is little value in that in most scenarios. There are a few laptop chassis that I am very fond of and have wished I could "use that chassis with that hardware", but even then I haven't seen Framework chassis designs that give me that impression. I'm not saying they're crappy, but I'm thinking of different types of brushed metal, magnesium alloy stuff, etc.
Replaceable GPU and CPU is the big draw draw for me. Heck, the config nature of the shop also means I can chop off buying ram and memory instead of haggling with the store, since I have quite a few spare sticks lying around.
